Practical references on documentation, analytical methods, storage, and research-use standards. Written by the team that runs the assays.
A COA is only useful if you know which fields matter. This guide walks through identity confirmation, purity determination, lot and expiration tracking, and the chromatograms behind the summary numbers, plus the fields worth questioning before you accept a result.
Read the guide →The regulatory boundaries around RUO material, what qualified-buyer status requires, and how acknowledgment protects both parties.
Temperature ranges, freeze-thaw limits, light sensitivity, and reconstitution practices that keep a lot performing to its stated purity.
